Question

In track and field, the 440-yd. race was replaced with the 400-m race when Canada changed from the imperial system to the SI system. Which race is longer and by how much? Use the exact conversion: 1 yd. = 0.9144 m​

Answer 1

The 440-yd race is longer than the 400-m race by 2.336 meters.

Explanation:

We can convert the distance of the 440-yd race to meters using the conversion factor 1 yd = 0.9144 m:

440 yd = 440 x 0.9144 m/yd = 402.336 m

Therefore, the 440-yd race is 402.336 meters long.

On the other hand, the 400-m race is already in meters.

Comparing the two distances, we can see that the 440-yd race is longer than the 400-m race.

To find out by how much longer, we can subtract the length of the 400-m race from the length of the 440-yd race:

402.336 m - 400 m = 2.336 m

Therefore, the 440-yd race is longer than the 400-m race by 2.336 meters.
